Interesting , there were also the nobel prize winners and the presidential medals of smth this year , there are good reaches there , here I'm very impressed I had no idea for any of the subjects.

I'm thinking that data storage and the ethanol translation will be the most technologically valuable , Planet X is interesting and a fun concept still not finished , rivers in the core are quite the thing , I can't understand how you can measure that from surface temperature or. Anyway Thank you L) !
